The scores of a batsman in ten innings are : 38,70,48,34,42,55,63,46,54,44. Find the mean deviation about the median.

Explanation

`38,70,48,42,55,63,46,54,44`

Arranging `: 34,38,42,44,48,55,63,70`

Median `=frac{frac{x}{2}, frac{5}{2}+1}{2}=frac{5,6}{2}=`

`=frac{46+48}{2}=47`

Mean deviation

`=|34-47|+|38-47|+|42-47|+|44-47|`

`+|46-47|+|48-47|+|54-47|+|55-47|`

`|63-47|+|70-47|`
